Viral RNA replication depends on translation of the genome in cis, that is, a particular viral genome must be used first as a template for translation to become competent for RNA synthesis (Novak and Kirkegaard 1994).o examine the interplay between translation and RNA replication, we have used poliovirus as a model, because both in vitro and in vivo systems are available to dissect the viral cycle (Molla et al.
